LG5

The LG5, or 6H, is an inline-six cylinder 7. 8 L (476 cu in) engine. It is a commercial-grade vehicle engine and is currently operating in over 300,000 Isuzu and GM-built trucks, including the H-Series and T-series vehicles. It is mated to the Allsion 3000 and 3500 Series transmissions.

The following trucks use the LG5:

LB7

The LB7 was the first to be introduced in 2001. The V8 engine is a 6. 6 L (402. 8 cu in) and it has 300 hp (224 kW) and 520 lb·ft (705 N·m) of torque. It is a 32-valve design with high-pressure common-rail direct injection and aluminum cylinder heads.

The Duramax was on the Ward's 10 Best Engines list in 2001 and 2002. Ward's 10 Best Engines is an annual list of the ten "best" automobile engines available in the U

The following trucks use the LB7:

LLY

The LLY (internally called the 8GF1) is a 6. Robert Bosch GmbH is a German diversified technology-based corporation which was started in 1886 by Robert Bosch in Stuttgart Germany. 6 L (6599 cc) turbocharged engine which debuted in 2004 in GM trucks. A turbocharger, or turbo, is an air Compressor used for forced-induction of an Internal combustion engine. It is a 32-valve design with high-pressure common-rail direct injection and aluminum cylinder heads. In Automotive engineering, an engine is referred to as multi-valve (or multivalve) when each cylinder has more than two valves. Output is 310 hp (231 kW) at 3100 rpm and 605 lb·ft (820 N·m) at just 1800 rpm. The engine was released with a new Garrett turbocharger with a variable geometry vane system. The valve covers were scalloped to allow access to the injectors without having to remove the valve covers, saving significant labor costs if injector replacement became necessary, and preventing leaked fuel from entering the crankcase, causing oil dilution.

The following trucks used the LLY engine:

Specifications

LBZ

The LBZ is nearly identical to the LLY engine. Robert Bosch GmbH is a German diversified technology-based corporation which was started in 1886 by Robert Bosch in Stuttgart Germany. It is a 6. 6 L turbocharged engine and was introduced in 2005 for the 2006 and early 2007 model years. Its output is 360 hp (268 kW) at 3200 rpm and torque is 650 lb·ft (881 N·m) at 1600 rpm. It's mated to a new Allison 1000 6-speed transmission.

The following trucks have or are due to have the LBZ engine:

LMM

The LMM specifications are nearly identical to the LBZ engine. Robert Bosch GmbH is a German diversified technology-based corporation which was started in 1886 by Robert Bosch in Stuttgart Germany. It is a 6. 6 L turbocharged engine and was introduced in 2006 for the 2007. 5 model year. Its output has seen a slight increase of 5 hp (4 kW) and 10 lb·ft (14 N·m) of torque over the LBZ. This makes it 365 hp (272 kW) at 3200 rpm and 660 ft (201 m)·ft·lbf of torque at 1600 rpm. It's mated to an Allison 1000 6-speed transmission.

The LMM Duramax 6. 6L V-8 has new equipment to help it meet the US EPA mandated 2007 emission standards. Emission standards are requirements that set specific limits to the amount of Pollutants that can be released into the environment The new standard requires a 90-percent reduction in particulate matter (PM), compared with the previous standard, implemented in 2004, and a 50-percent reduction in oxides of nitrogen (NOx). Particulates, alternatively referred to as particulate matter (PM or fine particles, are tiny particles of solid or liquid suspended in a gas The term nitrogen oxide typically refers to any Binary compound of Oxygen and Nitrogen, or to a mixture of such compounds Nitric The use of reformulated, ultra-low sulfur diesel fuel, which went on sale nationwide in the fall of 2006, is required to meet the new emissions standard and prevent damage to the emissions equipment.

General Motors plans a 4. 5 L V8 for light-duty applications which will be built at GM's powertrain facility in Tonawanda, New York after 2009. The name Tonawanda refers to several locations in Western New York. Designed to fit in the same space as a Chevrolet Small-Block engine, it is expected to produce over 310 hp (231 kW) and 520 lb·ft (705 N·m) of torque. Introduction Chevrolet 's Small-block V8 is a famous Automobile engine The small size should allow the engine to be used in a variety of applications, depending on market demand, though it would initially be targeted for the Chevy Silverado/GMC Sierra and Hummer H2. The Hummer H2 is an SUV and SUT manufactured by General Motors under the Hummer brand [2] Unlike previous Duramax engines, the 4. 5 liter will be designed and built entirely by GM, without assistance from Isuzu.
